FINISHING AND REFINISHING INSTRUCTIONS
for Interior and Exterior Door Slabs and Systems (JCM004)
PREPARE THE DOOR
If renishing a previously nished door slab, use the following recommendations for the product you have. The achieved result will depend on the skill 
of the person doing the renishing. We recommend seeking the help of a skilled professional if unsure. After preparing the previous nish, follow the 
nishing instructions in the following sections.
Doors that were Painted Doors that were Stained
Steel and 
Smooth Pro 
Fiberglass
1. Scuff sand with 150 grit sandpaper or ner or buff the surface 
of the door thoroughly with 0000 steel wool until the entire 
surface is dulled and even. Feather out areas where the previous 
nish is cracked or peeling by removing all loose material and 
sanding outward until the surface is uniformly level.
2. Remove all loose debris with tack cloth (available in store paint 
sections) and re-prime bare areas with a good quality water-
based primer appropriate for the substrate. Re-priming the 
entire door will provide the best surface for the new top coat.

1. Scuff sand with 400 grit sandpaper or buff the surface of the door thoroughly with 0000 steel wool until the entire surface is dulled

until the surface is uniformly level.
2. Remove all loose debris with tack cloth (available in store paint sections) and re-prime bare areas with a good quality water-based 
primer appropriate for the substrate. Re-priming the entire door will provide the best surface for the new top coat.

PREVIOUSLY UNFINISHED PRODUCTS
•  If the door slab has a glass insert, install the provided screw covers 
over the screw heads around the glass insert.
•  Clean the door with a clean, lint-free cloth, removing all dust and 
foreign debris. For light cleaning, a one part vinegar to ten parts 
water mixture can be used. For tough dirt removal, use denatured 
alcohol making sure all residue is removed by turning the cloth 
often while cleaning. Allow the door to dry thoroughly. DO NOT USE 
SANDPAPER OR LACQUER THINNER ON ARCHITECTURAL OR DESIGN/
SMOOTH PRO FIBERGLASS, OR FINISHIELD
®
 DOORS.
For Wood Doors Only:
•  Before applying rst nishing coat, lightly block sand with the grain 
all surfaces by hand with 400 grit sandpaper. Remove all handling 
marks, raise grain, scuffs, burnishes and other undesirable blemishes. 
For doors with wood veneers, veneers are very thin and it can be 
easy to sand through the veneer. Do not sand veneers any more than 
necessary.
•  Stile and rail doors have wood panels that can oat. If necessary, 
adjust panels before nishing by carefully realigning with a wood 
block and hammer.
FINISH THE DOOR
Use the table below to nd your 
product and desired nish and 
follow the instructions in the 
corresponding box. The illustration 
to the right shows the recommended 
order to apply nishing materials 
to the door by any method except 
spraying. Finishing materials should 
be rst applied, in the direction 
of the arrows, to the door panels 
(1), then to the vertical members, 
or stiles (2), horizontal members, 
or rails (3) and nally to the outer 
stiles (4). This method has been 
tested to yield the best results. You 
may, however, use any method that 
youchoose.
